How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 57 = 10.26
  3. Check: Work backwards: 10.26 ÷ 57 × 100 = 18%.

Another method. As a proportion of part to whole: 18/100 = part/57, so part = 18 × 57 ÷ 100 = 10.26. Both methods always give the same answer.

In a spreadsheet: =18%*57. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

10.26 is the 18% share of 57. The remaining 82% is 46.74, and the two parts add back up to 57.

Discounts: 18% off an item priced $57 saves $10.26, so you pay $46.74.

Adding and taking away 18%

Increasing 57 by 18% gives 67.26 and decreasing it by 18% gives 46.74. These do not cancel out: raising 57 by 18% and then lowering the result by 18% ends at 55.1532, because the second 18% is taken of a bigger number.
